I use a camelback for both my road rides and commute. I don't care for the weight on my back, but found that I hydrate more consistantly with the camelback. I have a small bike and am lucky to be able to fit two full size water bottles on my bike, but I can't reach the bottles and put them back easily while riding. I have the magic and just bought a new magic where I can fill the bladder without taking it out. I will use that one for my longer rides and use my old one for my commutes.
